MECHANISM FOR CLOSING AND OPENING SAFE-DOORS.

SPECIFICATION forming part of Letters Patent No. 463,698, dated November24, 1891.

Application filed August 10, 1891. Serial No. 402,260- (No model.)

To collwhorn it may concern:

Be it known that I, IVILLIAM CORRY, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Mechanism forClosing and Opening Safe and Vault Doors, of which the following is aspecification.

This invention relates to safes, vaults, and similar receptacles; andthe invention consists in means for opening and closingthe door, ashereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a front elevation of a safehaving my improvements applied-thereto. Fig. 2 is a similar elevationtaken at right angles to Fig. 1; and Fig. 3 is a transverse horizontalsection on the line a: a of Fig. 1, showing the door swung into positionand ready to be forced into place.

This invention is designed to be used in connection with that class ofdoors on safes and vaults which are provided with interlockingprojections engaging in corresponding grooves in the jambs of the body,or vice versa, or both, and which necessitates moving the door bodilystraight in and out in closing and opening the same 'in a manner wellunderstood, the door being for that purpose hung on double hinges, asusual in such cases.

In Patent No. 363,118, granted to me May 17, 1887, I describedpressure-bars applied to the doors of safes, &c., with inclinesoperating to force the door in and out, and my present invention isdesigned to provide means for operating the pressure-bars and'at thesame time secure a positive and uniform movement of the door and bywhich the attendant can exert great force thereon. 7

In the drawings, A represents the body of a safe; B, the door; C, thehinges, and D the pressure-bars, which are secured upon the outer faceof the door and have one end inclined to engage in an inclined socket ina clip d, firmly secured to the wall or body near the edge of the doorin the same manner as described in my former patent above mentioned, itbeing provided with friction-rollers r, as therein described and asshown in Fig. In the former patent these pressure-bars were providedwith an inclined slot at their rear ends to force the door in and out atthat side; but in the present case I dispense with this, the rear end ofthe pressure-bars D stopping short of the edge of the door, as shown inFigs. 1 and 2, their face for some distance being provided with teeth,as shown more clearly in Fig. 3, which engage with pinions h, journaledin brackets J, secured to the front of the door, the bar D sliding in arecess in the brackets in rear of the pinions, there preferably being afriction-roller q" seated in the bracketin rear of the bar, as shown indotted lines in Fig. 3. To each of these pinions h is rigidly secured anarm is, which has a slot in it, as shown in Fig. 3, there being one ofthese pinions and slotted arms for each pressure-bar, of which two areusually applied to the door, as shown in the drawings, though more maybe used, if desired. To the face of the door at its rear edge I securetwo or more brackets I, which are also provided with a slot, as shownclearly in Fig. 3. To operate these various parts I provide two leversL, which are hinged or pivoted at o to brackets f, firmly secured to thewall or body A, these being so located that their pivot or journal 0, onwhich the levers are hung, shall be in line with the edge of the door,as shown in Fig. 3. These levers are connected at their opposite or freeends by a handle-bar H, by which they are moved when desired. Eachlever, as shown in Fig. 3,is provided with two pins n and m, the formerbeing arranged to engage in the slot in the pinion-arm k and the latterin the slot in the bracket I on the door. with these devices thusarranged it will bev seen that when it is desired to close the door itis first swung on its hinges to the position shown in Fig. 3, when bypressing on the handle-bar II the levers L are forced inward toward thedoor. The pins m, moving in their slots, operate to press or force thedoor inward at its rear edge, the pins n at the same time pressinginward the ends of arms 70, and thereby turning the pinions h, the teethof which, engaging with those of the pressure bars, shove the latterendwise, their inclined ends engaging in the sockets of the clips at andforcing the door inward at that edge also, the parts all movingsimultaneously and working together to force the door into its seat withgreat force. To open the door or draw it out of its closed position, itis of course only necessary to reverse the movement by pulling thehandle-bar ll outward. It is obvious that this method of operating thepressure-bars by means of the pinions and the levers L may be appliedwith equal facility to the pressurebars (described and shown in myformer patent) with inclines at both ends; but in that case the slottedbrackets I on the door and the pins m on the levers L might be dispensedwith, as their functions would be performed by the inclines at the rearends of the press ure-bars.

\Vith doors of the ordinary size I make the pressure-bars of a singlepiece, as shown in the lower part of Fig.1; but for the larger orodd-sized doorsI may make them in two parts and unite them by a nut orthimble a, provided with a right and left handed thread, by which meansthey can be adjusted to work with perfect accuracy. \Vhen once adjustedthe nut a will be fastened by a set-screw t' or by a wedge Z, as shownin Fig. 3, or by locknuts.

The bolt-work is mounted in a frame F, secured to the inner face of thedoor in such a position that when the door is fully closed the ends ofthe bolts ewill engage against the inner face of the walls around thesides and ends of the door, this frame, with its bolts e, being shown inFig. 3. Any suitable style of bolt-work may be used and any style oftime or other lock may be applied to lock theboltwork.

This invention is of special advantage in large safes and vaults, inwhich large and heavy doors are used. Itis obvious that more than twopressure-bars may be used, in which case, of course, the number ofpinions and levers will be correspondingly increased, and that in smallsafes a single pressure-bar may be applied and operated in the samemanner. The great power exerted by the means described enables the doorto be closed very tightly, so as to leave no space or crack for theinsertion of explosives, and especially so when rubber or other elasticpacking is used in the grooves or joints.

Having thus fully described my invention, what I claim is- 1. Incombination with one or more pressure-bars applied to the door of asafe, vault, or similar receptacle, a pinion arranged to engage with andmove said pressure-bar, said pinion being provided with an arm foroperating the same, and one or more pivoted levers connected to thepinion-arm, substantially as described, whereby the movement of thelever is made to impart an endwise movement to the pressure bar or bars,as and for the purpose set forth.

2. In combination with a safe or vault and its door, one or morepressure-bars adapted to press the door in and out at one edge, one ormore brackets applied to the door at or near its opposite edge, one ormore pinions arranged toengage with the pressure-bars, and one or morepivoted levers arranged to engage with the brackets and with the arms ofthe pinions, the combination and arrangement being substantially asshown and described.

In witness whereof I hereunto set my hand in the presence of twowitnesses.
